Be it known {that LJAMES F; STRUBLE, a"

citizen of the United States, andres-ident of Hutchinson, in the county of Reno and State of Kansas, have invented certain new'j "and useful Improvements in VVind-niiflls, of which I the following is a specification.

This invention relates towindm-illsand more particularly to the power transmission thereof. I a

"Briefly stated animportant object is to provide novel means whereby tusta'bilize the action and movement of the transmission housing sothat the same is efficiently operated and without excessive wear. I v

' A further object isto provide a indmill having" a n'ovel' form of shaft supporting means which is at all times maintained "in a well lubricated coiidition,

Furthermore the inventionforming-the subject matter of this application is provided with a novel form, oisplit-washer or pack- Y ingmember which may lie-applied to the main power transl'nission shaft after the installation ol' the same. y Other obyectsand advantages will be ap-' parent "during the course of the following description v V r. "Inthe accompanying"drawing formingv a part of this application and 1n VVhlCll llkQ numeralsare employed' to-designate like parts throughout the same, j Figure 1 is afragmentary side elevation of the'impr'oved windmill. 7 l

' Figure 3 is-an enlarged frag ientary' side elevation of the windmill, parts being shown in section. I I o In the drawing the rotatably supports a turn table '6. Figure 3 illustrates that an annular series of antifrlctlon elements 7 are-arranged 1n raceways o-f-the opposed faces of the'tower 5 and .the

turntable 6' so as to permit theturn table 'to rotate with 'a'minimurnof resistance, I

ous series of teeth with which the teeth of a pinion 1.4 mesh The pinion 1 L is I numeral 5- generally designates a tower; the upper end of which lfi andwhen'the po'vveif-ishafft lis turned the o mounted uponone iendof the pinion will cause the rack iambe. moved 1 vertically; The1shaft-16 is provided (mopposite sides of the apinion l with bearings I I 18 i which slide within channels :Oir, grooves 20 and thereby hold the teeth" of the pinion i :14 in engagement with the 2 teeth of the rack my; several co+pending applications, for

patents I illustrated a spring-ate maintain the pinion and the rack properly; in mesh at all times and-it was foundthat the spring would soon wear and :exertan undesirable tension when the ;-11ousing.:was ,down :and exert, in-

suflicien-t tension when the housing wasup',

.JThe1BfOIe, :I have provided a stabilizing cable 30 which :is trained about va .pulley 32 a v and is :provided at one! end with a sectional weight 33.

During vvthe ,ver't'ical, movement. -ot the at I the: end. of ,its movement in; either direction the weightedgcablefiQ will exert a uni.- form tension I on, J the, housing and thereby maintain the rack13andthe pinion, prop? transmissionihousing and when 'thefsame is 'erly in: mesh. r As jtheucabgle ,30 is connected to the transmission housing ,1-2, at the vertic'alcenter of the. same .it is normally dis;

posed: in line with the pum rod 1050 that theirack 13 which, at times, partakes of a slightdlateral movement isurged,int0 -engagement with the teetln jotvthe. apinionfl i. In other'words the weight on the cable;;30

willwexerta constant and uniform tension so thatuproper. connection ibetween the pinion-14: and the rack may be. maintained It 1 I will be seenthat regardless ofgwhether the continuous, rack member isrupo or down, on the :right I or left; hand side of the; pinion 1,4,

the tension} exerted by r the weighted cable 30 will be'the same. 7

In carrying out the invention a tubular standard 36 is mounted upontheturn table 6 and is'provided with brackets 37-;which. ro-

tatably support therolleror pulley'32i Fig: ure 3 illustrates that: the cable E 0 .p asse's freely through the tubular standard 36 and has connection with .the weight 33, at its loweriendr. p

The weight;33 mayconsist otapluralityofsections separately mounted upon the rod 37* so that the weight maybe increased or lessened as the occasion requires. Also a spring 38 is mounted upon the lower portion of the rod 37 7 andprovides a cushion c0nnection between the weight and the rod so that in case the weight comes to a sudden stop the strain will, be reduced to a minimum. The downward movement of the weight is of course limited by the cable 30 and a safety cable 40 is connected to the looped upper end of the rod 37 and to the under side of the turn table. It is believed to be obvious that in case the cable 30 breaks the weight of the member 33 will be borne by the cable 40.

The main power transmitting shaft 16 is extended through aligned bearings 41 mounted in a bearing casing 42 secured upon the turn table 6 in any suitable manner. Figure 3 illustrates that the central portion of the bearing housing 42 is provided with an oil reservoir 44 and the bushings 46 secured upon the shaft are formed with oil ducts or passages 47 by means of which oil is supplied to the several bearings. The 011 is supplied to the several bearings 40 by means of the oil ducts 47 and the oil upon returning contacts with the bottom walls 48 at the ends of the casing and then flows back to the'reservoir 44. The bottom walls 48 are inclined downwardly and inwardly toward the reservoir 44. The oil reservoir 44 which may contain a suitable quantity of oil is provided with a cover plate 50 which may be conveniently detached when desired for the purpose of adjusting the bushings or thrust members 46 longitudinally on the shaft 16 to compensate for wear. Set screws 53 are employed to hold the thrust members 46 in a set position on the shaft and as wear occurs the thrust members may be adjusted longitudinally. Suitable packing members are located at the outer ends of the bearings 40 and consist of a pair of coacting fiat sections having their ends in overlapping relation.

With reference to the foregoing description taken in connection with the accompanying drawing it will be seen that a windmill constructed in accordance with this invention is of very simple construction and operatlonsince the transmission housing 12 is at all times maintained in its proper position.

Having thus described the invention, what is claimed is 1. The combination of a tower, of a turn table supported thereon, a tubular housing mounted upon the turn table and having its upper end provided with a pulley, a weighted cable extending through said housing and trained about said pulley, a power transmitting member connected to said cable and having a continuous rack, and a power transmitting pinion arranged in said transmission and having engagement with said rack.

2. A windmill comprising a tower, a turn table mounted thereon, a transmission movable through the turn table and having a continuous rack and oppositely located channels at opposite sides of the rack, a main pinion in engagement with the rack, a power transmitting shaft connected to the pinion and having bearings locatedlin said channels, a Weighted cable connected to said transmission for constantly urging the same upwardly, said cable being connected to the vertical center of said transmission, a tubular standard mounted upon the turntable and having a pulley, the cable being trained about the pulley and extending through said standard, and a pump rod connected to the lower portion of the transmission at the vertical center of the same.

3. A windmill comprising a tower, a turn table mounted thereon, a transmission movable through the turn table and having a rack provided with an endless series of teeth, a pinion engaging said teeth and ada ted to move the transmission ver tica ly and late-rally, a cable connected to the vertical center of said transmission, a weight connected to the cable and adapted for urging the transmission upwardly, a tubular standard mounted upon the turn table and having a pulley about which said cable is trained, means providing a yieldable connection between the weight and the cable, and a pump rod connected to the transmission at the vertical center of the same.

4. A windmill comprising a tower, a turn table mounted thereon, a transmission movable through the turn table and having a 100 continuous rack member, a pinion engaging said rack member and adapted to move instead the transmission vertically and laterally, a cable connected to the vertical cen ter of said transmission, a weight connected 105 to the cable and adapted to urge the transmission upwardly, a tubular standard mounted upon the turn table and having a pulley about which the cable is trained,

means providing a yieldable connection be- 110 tween the weight and the cable, a pump rod connected to the transmission at the vertical center of the same, and a main shaft connected to said pinion and having bearings engaged with the interior of the trans- 115 misslon.
